BRUNO BOHME, OF DRESDEN, GERMANY.

CUTTING-MACHINE.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed November 16, 1906. Serial No. 343,745.

To all whom it may concern:

Be it known that I, BRUNO Bonnie, paper-cutter, a subject of the GermanEmperor, and resident of Dre'sden, Germany, have invented new and usefulImprovements in and Relating to Cutting-Machines, of which the followingis a specification.

The subject of the present invention is a device to be fitted to cuttingmachines, and which is adapted to allow any number of uniform strips,labels, and the like to be cut from paper, cork plates, silks and thelike.

The feature of the invention on the one hand is that a plate which isimmediately in front of the cutting blade and against which rests thefront edges of the material to be cut, is so mounted as to be able to beturned over in an acute angle, and on the other hand the whole devicecan be moved backwards and forwards by means of a laterally movable bar.

In the accompanying drawing Figure 1 is a plan View of the device. Fig.2 is a side view of Fig. 1. Fig. 3 is a plan of the device. Fig. 4 is aside view of Fig. 3. Fig. 5 is a rear view of the device. Fig. 6 is amode of operation of the plate for supporting the cut material; thisplate we will call the support plate.

Screwed to the table a of the paper cutting machine are scales 7) onwhich hollow slides 7 slide or may be fixed The plate 7) slides in thehollow slide 1'. The support plate 0 is hinged to the fore broad side ofsaid plate I). The latter is further furnished with adjustable bars (Iand an adj ustable disk 9 furnished with a handle. This disk g is soconnected to the bars (I by means of arms 6, that a 1'0- tation of thedisk 9 either moves the rods d towards or away from each other.

The object of this mechanism isto place the support plate a, which isheld under tension by the springs 2', in a vertical or slanting positionas shown in Fig. 3 and 4.

In order to be able to move the whole device backwards, the plate I) isprovided with sockets p in which the rod 0 is free to slide laterally.This rod 0 is fm'- nished at both ends with a nose s, the outer slantingface of which slides up or down the corresponding shaped side of theblock 15 screwed in the hollow slide 1'.

It follows therefore that by sliding said rod 0 to the right hand side,the whole device is moved forwards, and by moving the rod 0 in theopposite direction the device moves backwards.

The turning support plate 0 allows any number of strips of uniformbreadth to be continually out without having to reset the size, andstrips of the least possible width do not fall but rest up against theslanting support plate 0. Thus the tedious job of collecting the stripswhich would otherwise fall over, is obviated. Another advantage of thissupport plate is that the cut material yields to the penetration of theknife, consequently damages caused by jamming are prevented. One isfurther able to see, by turning back the support plate 0 before cutting,if the layers of the material to be out are in position. v

The rod 0 would be particularly useful when cutting soft material, suchas foliated gold, tin foil and the like, or if the knife head projectsto any extent, it e. if the knife is worn down, as the space between thedevice and the knife may be increased by means of the shifting rod 0.

Having fully described my invention, what I claim and desire to secureby Letters Patent is:

1. A device to be fitted to cutting machines, comprising, in combinationthe support plate (0). hinged to the base plate (11,) and held undertension by springs i,) and adapted to be placed vertically to thecutting surface or in an acute angle to the same by means of anadjusting disk (9) provided with arms (0) which are connected to rods(d), substantially as described and shown and for the purpose set forth.

2. A device to be fitted to cutting machines comprising, in combination,the support plate (0) and plate (b) which slides in the slide (1') whichis adjustable on the cutting table, and the support plate (0) and plate(1)) adapted to be moved forwards and backwards by laterally sliding therod 0 furnished at both ends with noses (s) substantially as describedand shown and for the purpose set forth.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing; witnesses.
